Causes and Solutions to Human-Caused Air Pollution
This paper examines the primary sources of air pollution resulting from human activity and surveys recommended strategies for reducing it. After briefly distinguishing natural from human-caused pollution, the paper focuses on four major contributors: fossil fuel-burning automobiles and power plants, industrial incinerators, coal-fired power plants, and large-scale agricultural operations. Drawing on sources including the EPA, Greenpeace, and the Sierra Club, the paper outlines specific policy measures and individual actions—such as reformulated gasoline programs, sustainable waste management, energy conservation, and reduced use of agricultural chemicals—that can meaningfully lower harmful emissions.

What makes this paper effective
- The paper efficiently narrows its scope in the introduction, clearly explaining why it focuses on human-caused rather than natural pollution, which orients the reader immediately.
- Each major pollution source is supported by a specific, cited statistic (e.g., coal plants contributing 96% of sulfur dioxide emissions), giving the analysis concrete grounding.
- The paper consistently pairs problem identification with recommended solutions, creating a balanced cause-and-response structure throughout.
Key academic technique demonstrated
The paper demonstrates effective use of authoritative organizational sources—the EPA, Greenpeace, and the Sierra Club—to lend credibility to each claim. Rather than relying solely on primary data, the writer synthesizes positions from multiple advocacy and regulatory bodies to build a converging argument that air pollution demands policy and behavioral intervention.
Structure breakdown
The paper opens with a brief definitional introduction that distinguishes natural from human-caused pollution, then moves through four discrete pollution sources in separate sections. Each section follows a consistent pattern: identify the source, cite statistics on its impact, and present recommended mitigation strategies. A short conclusion summarizes the agricultural dimension. The structure is clear and modular, making it easy to follow despite the breadth of topics covered.
Introduction to Air Pollution
Air pollution arises from both natural processes and human activity. Substances not naturally found in the air—or present at greater concentrations or in unusual locations—are considered pollutants. Natural sources of air pollution include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds, and natural radioactivity.
Natural air pollution does not typically occur in concentrated quantities in particular locations. It is distributed throughout the world and, as a result, poses little threat to the health of people and ecosystems (1). The remainder of this paper therefore focuses on air pollution resulting from human activity, and on potential means of reducing it.
Automobiles and Fossil Fuel Power Plants
The biggest causes of air pollution are fossil fuel-burning power plants and automobiles. Combined, these two sources are responsible for approximately 90% of all air pollution in the United States. Due to the large share of air pollution attributable to automobiles, the Environmental Protection Agency has initiated a number of programs to reduce automobile emissions.
One of these initiatives is the Clean Air Act's reformulated gasoline program. Reformulated gasoline is blended to burn more cleanly and to reduce smog-forming and toxic pollutants in the air. The Clean Air Act requires that reformulated gasoline be used in cities with the worst smog pollution in order to reduce harmful ozone emissions (2).
The first phase of the reformulated gasoline program was designed to reduce the air pollution that causes smog by 64,000 tons per year in areas that use reformulated gasoline, compared to conventional gasoline. This reduction is equivalent to eliminating the smog-forming emissions from over 10 million vehicles (2).
Industrial Incinerators
Greenpeace has identified industrial incinerators as a major source of air pollution. According to Greenpeace, fifteen municipal waste incinerators burn 2.5 million tons of waste every year in the United Kingdom alone. These incinerators produce a range of toxic chemicals that can cause cancer, heart disease, respiratory problems, immune system defects, increased allergies, and birth defects (3). Greenpeace recommends sustainable waste management as an alternative to industrial incineration.
Conclusion
Air pollution stems from a variety of human activities, and reducing it requires action on multiple fronts—from transportation and energy production to industrial waste management and agricultural practices. Policy measures, technological improvements, and individual behavioral changes each play an important role in addressing this widespread environmental challenge.
